A 25-year-old Kansas City Chiefs player shot his girlfriend early Saturday, then drove to Arrowhead Stadium and turned the gun on himself as two team officials were confronting him, police said.

Kansas City police Supervisor Andrea Khan would not release the name of the player involved and the condition of the two parties was not immediately known.

Police spokesman Darin Snapp said authorities received a call Saturday morning from a woman who said her daughter had been shot multiple times at a residence about five miles away from the Arrowhead complex. Snapp said a call was then received from the Chiefs’ practice facility.

Upon arriving, Snapp said that police witnessed a black male in a car with a handgun to his head talking to two Chiefs officials. That’s when police heard a gunshot.

Arrowhead Stadium has been locked down since about 8 a.m.

“We can confirm that there was an incident at Arrowhead earlier this morning,” the Chiefs said in a statement. “We are cooperating with authorities in their investigation.”

The season has been a massive disappointment for the Chiefs, who were expected to contend for the AFC West title.
